BD Diesel Performance Automatic Transmissions

BD Diesel Performance automatic transmissions are designed to transfer the power from high-torque modified diesel engines. They feature redesigned clutch packs with 50 percent more holding surface, steel 6-pin planetary gear carriers, and new lube ports added for high-load areas. Shift strategies and pressure circuits are also modified to handle the high-torque applications. BD Diesel transmissions are not rebuilt factory transmissions--they are custom-tailored to work with your modified truck.
